Observe the argument the Lord is pleased to make use of, for more strongly enforcing the divine precepts that follow in this Chapter. He saith I am the Lord. The Lord, the Creator, the first self-existing cause of all. His authority therefore is indisputable, to command. But this is not all. I am the Lord that God; that is, thy God in a covenant way; the God of Abraham, Isaac, and Jacob in Exodus 9:25. Neither is this all. He asserts his authority not merely by right of Creation, and covenant engagements, but also by redemption: that brought thee out of Egypt. Reader! See whether you know God under these precious characters also: for then your language will be like that of the Psalmist, Psalms 116:16.
